The invention herein pertains to dispensing pellets used in pellet rifles and pistols and particularly pertains to a dispenser which can be worn on the belt of the user for convenience.
Target practice using air and spring operated pellet guns in recent years has become increasingly popular. Many pellet guns require a single pellet to be inserted each time after the gun is fired. Shooters in the past have often carried pellets in a loose fashion within their pockets or container. Some mechanical devices have also been tried with varying degrees of success for loading pellets directly into air operated guns. However, it is generally preferred to load pellet guns and the like by hand, especially for single shot rifles and pistols. However, the carrying of loose pellets is troublesome as lead pellets can be easily distorted during handling, making loading difficult and time consuming. Also, a loose pellet requires a certain degree of dexterity to be manually picked up especially if the fingers are cold during winter shooting.
Thus, with the problems associated with the prior pellet loading devices and realizing the needs which currently exist, the present invention was conceived and one of its objectives is to provide a handy pellet dispensing device which can be worn on the shooter's side for example, on the belt of the shooter.
It is another objective of the present invention to provide a pellet dispensing device and method of operation which will consistently deliver one pellet at a time, without jamming.
It is still another objective of the present invention to provide a pellet dispensing device which can be loaded with a large number of pellets selected for a particular caliber gun.
It is yet another objective of the present invention to provide a pellet dispensing device and method of operation which allows easy loading and trouble-free dispensing.
It is still a further objective of the present invention to provide a pellet dispensing device which is relatively inexpensive to manufacture and purchase.
It is another objective of the present invention to provide a pellet dispensing device which helps reduce exposure to lead by eliminating excess pellet handling.
Various other objectives and advantages of the present invention will become apparent to those skilled in the art as a more detailed description is set forth below.
The aforesaid and other objectives are realized by a pellet dispensing device preferably formed from aluminum and stainless steel. The dispensing device includes an outer aluminum housing having a clasp for convenient attachment to the belt of the wearer. A rotatable cylinder formed from aluminum having multiple pellet chambers is contained within the housing and includes a hopper positioned at the top thereof having a sloped bottom which is in communication with the pellet chambers. A threaded cap closes the hopper once the chambers have been loaded. To actuate the pellet dispenser a trigger is pressed which is located within the housing bottom. One pellet is then dispensed at a time through an exit conduit for use as ammunition in an air operated gun. On the bottom of the cylinder a series of detents or depressions are arranged in a circular fashion. A spring loaded sphere is mounted in the bottom of the housing which engages each detent in succession as the cylinder is rotated to insure precise chamber alignment with the exit conduit. To prevent more than one pellet being dispensed at a time, a means to engage a pellet in the form of a coil spring is attached to the trigger. The coil spring passes through an opening in the wall of the exit conduit to engage various sized lead pellets as are utilized from 0.177 to 0.250 caliber, so only one pellet at a time is dispensed.

FIG. 2 demonstrates a cross-sectional exploded side view of the dispensing device as seen in FIG. 1;
FIG. 3A depicts a cross-sectional view of the dispenser housing with the trigger in a dormant or open state;
FIG. 3B features the dispenser housing as seen in FIG. 3A with the trigger in a closed or actuated state;
FIG. 4 shows a top view of the cylinder with the cap removed as along lines 4—4 of FIG. 2; and
FIG. 5 shows a bottom view of the cylinder as along lines 5—5 of FIG. 2.
For a better understanding of the invention and its operation, turning now to the drawings, the preferred embodiment is illustrated in FIGS. 1-5 which shows pellet dispensing device 10 in FIGS. 1 and 2 having an outer housing 11 containing rotatable cylinder 12 therein. Cylinder 12 defines fifteen pellet chambers 13 as shown in FIG. 5 although other numbers of chambers and sizes could be utilized as desired. Atop cylinder 12 is hopper 14 for holding a multiplicity of pellets 20 for convenience and ease in loading chambers 13. Hopper 14 has a sloped bottom 22 which encourages pellets 20 to roll toward apertures 23 during loading and includes a plurality of interior threads for releasable engagement with threaded cap 15, as shown in more detail in FIG. 2. Dispensing device 10 is preferably, mainly formed by machining aluminum, although other suitable methods, metals and materials such as plastic may be used. Dispensing device 10 is preferably 2.25 inches (5.71 cm) in height with an outer diameter of 1.625 inches (4.12 cm) for a 0.177 caliber pellet dispenser.
In FIG. 2 a cross-sectional view of preferred pellet dispensing device 10 is shown in exploded fashion. Cap 15 having a knurled periphery 16 is removed from hopper 14 so pellets 20 can be placed therein. By gentle shaking, pellets 20 then randomly fall through apertures 23 into each of chambers 13 until full. Pellets 20 are conventional lead pellets as sold in various sizes such as 0.177, 0.200, 0.220 and 0.250 caliber (inches). Chambers 13 are sized to receive a 0.177 caliber pellet and of course other chamber sizes for other caliber pellets can be manufactured as desired.
Housing 11 includes bottom 17 having a trigger housing 18, all integrally formed. Trigger 19 is slidably mounted in trigger housing 18 as shown in FIGS. 2, 3A and 3B. Connecting rod 24 (FIG. 2) formed of stainless steel is provided with stainless steel C-clips 25, 25′ which maintain connecting rod 24 in place to hold cylinder 12 in housing 11. Connecting rod 24 extends somewhat downwardly beyond C-clip 25′ and resides in slot 28 of trigger 19 when assembled as seen in FIGS. 3A and 3B. Connecting rod 24 thereby guides trigger 19 during use. Resilient member 30 which is preferably a stainless steel coil spring fits within upper channel 31 on trigger 19 whereas resilient member 32 is also a stainless steel coil spring, but has a larger diameter and resides within channel 33 (FIG. 2). Upon assembly resilient member 32 contacts outer wall 37 of exit conduit 35 seen in FIG. 3B to apply return pressure to trigger 19 when actuated. Upon release, trigger 19 moves to its normal or deactuated position as resilient member 32 relaxes or expands. Slot 28 limits the movement of trigger 19 as it contains the terminal end of connecting rod 24, thus preventing excess trigger travel. Resilient member 30, which is a coil spring, passes through opening 36 in outer wall 37 to contact a pellet such as pellet P2 in FIG. 3B. By such contact, pellet P2 is restrained and will not exit trigger aperture 39. When trigger 19 is released, resilient member 32 forces trigger 19 rearwardly (right to left) as seen in FIG. 3A along with resilient member 30, to thereby release pellet P2 and allow it to fall and rest partially on top of aperture 39 of trigger 19. Pellet P2 is then ready to be released upon subsequent actuation of trigger 19 as shown in FIG. 3B. Pellet P3 will then pass through aperture 39 as trigger 19 moves from left to right as shown in FIG. 3B.
Aperture 41 in plate 40 as shown in FIG. 2 is misaligned with aperture 39 of trigger 19 before trigger actuation (see FIG. 3A). When trigger 19 is actuated (FIG. 3B) aperture 39 is brought into coincidental alignment with aperture 41 of plate 40 to allow pellet P3 seen in FIG. 3B to release therefrom. Thus, as trigger 19 is actuated, aperture 39 is brought into alignment with aperture 41 of plate 40, while resilient member 30 engages subsequent pellet P2 in exit conduit 35 as shown in FIG. 3B to prevent simultaneous, multiple pellet dispensing.
Once a chamber 13 (which is aligned with exit conduit 35) is empty the user can then index cylinder 12 manually by rotating hopper 14 by gripping knurled perimeter 43 as shown in FIG. 1 and turning cylinder 12. For accuracy in indexing cylinder 12 so that channels 13 are in precise coincidental alignment with exit conduit 35, detents 45 are defined in cylinder 12 as shown in FIG. 5. Detents 45 are preferably hemispherical in shape and engage sphere 46 as seen in FIG. 2. Sphere 46 is preferably formed from DELRIN (DuPont trademark for acetyl homopolymer) although other suitable polymeric or other materials may be utilized. Sphere 46 is positioned in and protrudes from channel 47. Channel 47 is spring loaded with resilient coil spring 49 which is held in place by stainless steel threaded member 50. Thus, as cylinder 12 is turned, detents 45 engage spherical member 46 contained within channel 47 in succession to provide accurate indexing and positive positioning of cylinder 12 whereby chambers 13 precisely align with exit conduit 35 to insure free passage of pellets 20 therethrough.
The preferred method of using dispensing device 10 includes the steps of removing dispensing device 10 from the belt (not shown) or other location by disengaging clasp 55 as seen in FIG. 1 which is attached to housing 11 preferably by two rivets or a spring retaining clip (not seen). While holding dispensing device 10 in one hand, cap 15 is released from hopper 14 by turning knurled periphery 16 in a counterclockwise direction with the other hand. Once hopper 14 has been opened, pellets 20 can then be placed in quantity in hopper 14. By gently shaking dispensing device 10, pellets 20 will randomly fall into all chambers 13 and each will fill to capacity. The first pellet 20 which falls into chamber 13 (FIG. 2 aligned with exit conduit 35) will pass into exit conduit 35 and rest atop partially exposed trigger aperture 39 (FIG. 3A). After all chambers 13 are filled, any excess pellets 20 can be removed from hopper 14 and returned to a container for storage. Cap 15 is then tightened onto hopper 14 by rotating cap 15 in a clockwise direction. Dispensing device 10 is then replaced and retained on the user's belt or the like with clasp 55. When it is desirous to dispense a pellet 20, trigger 19 is actuated (pressed inwardly) whereby pellet P2 resting on trigger aperture 39 as shown in FIG. 3A will fall from exit conduit 35 and pass through plate aperture 41, as shown by pellet P3 in FIG. 39 and is preferably caught by the user's hand for placement in a pellet pistol (not seen) or the like for firing purposes. Thereafter, by repeatedly depressing trigger 19, all pellets 20 in chamber 13 will be likewise dispensed, one at a time as resilient member 30 engages subsequent pellets 20 which pass into exit conduit 35, as the preceding pellet 20 passes through trigger aperture 39 and plate aperture 41. Once all pellets 20 in one chamber 13 are dispensed, cylinder 12 is manually rotated to the next chamber 13 and is secured in place by engagement of sphere 46 within detent 45. Trigger 19 actuation is repeated to empty that chamber 13. Thus, as each subsequent chamber 13 is emptied, cylinder 12 is rotated and the dispensing process repeated until all pellets 20 within cylinder 12 are dispensed. Cylinder 12 can then be reloaded as described, supra and the dispensing of pellets 20 continued as needed.
